Given that the cost of erecting a foundation for any building can be up to 40% of the total cost of construction, each individual developer wants to save on it. One way is to choose the optimal type of house foundation. This is one of the reasons why the pile foundation is so popular in the private sector.
It is possible to determine just how much the foundation costs on piles will cost approximately, since it depends on a number of factors, the parameters of which for each structure are different. This is due to the project, ground features and the like. Let us consider in more detail what affects the cost and what can be saved:
Materials
As a rule, screw piles of factory production are used as supports. They have different length and section, so you can focus on the price range from 900 to 2 100 rubles / pcs.
Optional
- Metal headband - from 220 rubles / pcs.
- Extension( if necessary) - about 450 rubles / m.
Making an estimate, for each pile you need to "pawn" about 2 800 - 3 000 rubles. But their number is determined not only by the overall dimensions of the structure, but also by the arrangement of supports, including the distance between adjacent products. As a rule, the interval between them is of the order of 1.5 - 2 m plus one at the "nodal" points( corners, junctions of walls, partitions, location of boiler units).The total cost of supports is easy to calculate.
Feature of the
project One of the drawbacks of the pile foundation is the cold floors on the 1st floor, as there is a wind blowing under the house. For the purpose of additional warming often the owners immediately mount and grillage( this is the base of the pile-tape).How to do it - another question. Some methods are described in detail here. Therefore, when drawing up an estimate, it is necessary to take into account the costs of these materials - wood, foam, waterproofing. Perhaps on a brick, if it is supposed to erect walls with single-row masonry + mortar. All this is easy to calculate, having become acquainted with the cost of consumables on the Internet.
If the "tape" will be built by employees, then their services will have to pay from 2,250 rubles / m.(depending on the height, together with earthwork).
Method of mounting
One of the advantages of such foundations is the ability to perform all work in a short time by own strength. On average, this will reduce costs by about half compared to hiring specialists.
Specialized organizations for assembling 1 pile will take at least 3 250 rubles. This together with the cementing and installation of the head( 320 + 105 rubles).
Total
* Exemplary data for a small building 6 x 6( professional services).
- Pile foundation - from 35 000 rubles.
- With grillage - from 105 000 rubles.
For more detailed drawing up of the estimate we will specify the average prices for some materials:
- cement - from 190 rubles / pack.(25 kg);
- ASG - from 300 rubles / m³;
- brick - from 14 rubles / pcs.
Conclusion - you can save a lot of money only if all the work on the foundation is done by yourself.
